Firstly welcome to the diabetes forum. Your B/G levels are certainly too high, but this will be also be raised with the throat infection and possible anti-biotics that you are currently taking. Having gone throught the course of the anti-biotics and hopefully overcome the throat infection, it should then give you a clearer idea as to your B/G levels.
Having a too high B/G level can bring about diabetic complications over a long term, by this we usually mean over a period of several years, though if possible it is always advisable to try to maintain B/G levels within the recognised safety bands on a daily basis, both before as well as 2 hours after eating.
Metformin is often the first choice medication for a Type 2, particularly if they happen to be overweight, but unfortunately Metformin even in it's slow release derivative dosen't always agree with the individual and can have a few nasty side effects.
Your former knowledge as a head chef in a hospital can now be put to good use, for you will know first hand the importance of the right hoice of suitable diabetic foods, their portion size, their GL loading effects, and this together with a regular modist daily exercise regime can only be of advantage to you in controlling your Type 2 diabetes.
p.s. I celebrated 'Burns Night' recently and my "haggis, tatties and neeps" didn't raise my own B/G..
